As shown particularly in Fig.v 5, the Ventilating fabric comprises a series of comparatively coarse or thick warp threads 26 and weft threads 21 spaced considerably apart to form comparatively large openings, the openings being partially closed by the interwoven coarse or heavy thread 2B twisted about thewarp and weft threads and serving to prevent such displacement of said warp and weft threads under such stressv as might tend to change the sizes or shapes of the openings. f Y

Each of the side Ventilating sections 20 as shown in Figs. l and 6, comprises the pleat 30 and Vthe exposed triangular sections 3| and 32 arranged respectively in front of and at the rear of the pleat. Between the rear edge 33 of the pleat 30 and the front inclined edge 34 of the rear triangular exposed side section 32, there is thereby arranged three thicknesses of material..

Similarly, between the front edge 36 of the pleat 30 and the rear edge 3l of the front triangular exposed section 3|, there is also provided three thicknesses of material. a multiplicity of thicknesses, the Ventilating secwhere the stressthereon is greatest andfurther, substantially the same degree of rigidity and flexibility Yas there is in the remaining fabric crown .pleats 2| and 22 is provided in the Ventilating A' section, whereby the proper shape of the cap.

To secure the top edge of the section in place in its proper position, said edge is laid in re-4 verse position on the crown edge surrounding the opening into which the Ventilating section is to be arranged, and then themarginal portions of suitable width of the ventilatingsection and the crown fabric vare secured-together by means of suitable stitching such as the overlooking stitching 45 (Figs. 2 and 6). turned back into their iinal positions andagain secured by the stitching 46 passing through the By so providing be permitted by the state of the prior y*art Yan The parts are then.

Ventilating section and through the infolded flap 41 of the crown fabric and through the outer crown fabric 48.

After the Ventilating sections have been sewn in place at the sides of the cap, it will be seen that said Ventilating sections stand above the sweatband in such position that they are not in Contact with any part of the head of the wearer whereby the air may enter freely through the interstices 5U of said Ventilating sections and circulate about the head and throughout the interior of the cap. The head of the wearer is thereby kept comparatively cool though adequately protected from dirt, grease, rain and the like. It will also be noted that by reason of the comparatively coarse threads from which the ventilating sections are formed and the peculiar weave thereof. said sections are just as flexible lbut not more so than the crown fabric and therefore maintain the proper shape of the cap just as -though .the capv were made entirely lof .the

closely woven crown fabric.

In that form of my inVention shown in Fig.

the Ventilating section 5| replaces'jthe closely Woven fabric pleat 2| as well as the triangular portions of the crown fabric. adjacent the pleat in the same manner as described in connection with the side Ventilating section 20. l'

A similar rearventilating section may be used,

if desired, to replace the pleat 22 (Fig. 1)Y and to insure circulation of air from the front'tothel rear of the cap and vice versa. The construction and means for securing the section 5| in place being identical with that hereinbeforedescribed in connection with the section 20, the description thereof need not be repeated.

Y As shown in Fig. 4, the Ventilating sections 52' and 53 may each be arranged between the front fabric pleat 2| and the side fabric pleats 54' and 55 respectively. In that case, the Ventilating sections are substituted for the unpleated crown fabric in such a manner as to induce avcircula.-l

tion of air at the front of the cap above the head of the wearer and thereby to induce circulation throughout the entire interior of the cap. Since the means for securing the edges of the sections 52 and 53 Vto the crown and to the sweatband are similar to that hereinbefore described, the description thereof need not be` repeated.

It will beiseen that I have provided a simple though extremely economical `and eiiicient4 cap designed to permit circulation of airabout the top of the head of the wearer and arranged above the sweatband lof the cap and having the same flexible and lshape-supporting properties as the fabric of the remaining crown of the cap', being in addition water-repellent and presenting an excellent appearance and therefore Well adapted to meet the severe requirements of practical use.

While I have shown and described certain specific forms of my invention, I do not wish to be understood as limiting myself thereto Vsince I intend to claim my invention as broadly as may the scope of the appended claims.

I claim: 1.y In a cap, a sweatband comprising a pair of separate similar sectiona: a pleated crown of` closely woven fabric, said crown having an opening therein, and a pleated section of loosely. woven fabric providing interstices therein ar-Y 2. A Ventilating cap comprising a sweatband having an outer and an inner section each having infolded upper and lower edges, a closely woven fabric crown provided Vvith a multiplicity of pleats each of substantially the height of the crown and each of substantially the same width as the height thereof, said crown having a trapezoidal opening therein extending over an area equal to the area of one of said pleats together with additional triangular side extensions, the edges of the crown adjacent the opening being infolded, and a section of loosely woven fab-ric comprising a Ventilating area arranged in said opening, said section being pleated to correspond to the remaining pleats of the crown and thereby providing three thicknesses of material at the overlapping portions of the pleat therein, and having exposed triangular extensions of a single thickness, the upper edge of said Ventilating section being secured to an infolded edge of the opening in the crown by overlapping stitching and by an additional line of stitching passing through said section and through the crown and the infolded edges thereof, and the lower edge of said section being secured between the upper infolded edges of the sweatband sections by a line of stitching passing through said sections and the infolded edges thereof.

3. In a cap provided with a pleated crown, a Visor, and a sweatband joining the crown and the Visor, a pleated Ventilating section in the crown providing a plurality of thicknesses of Ventilating material at the pleat thereof, and spaced triangular areas of a single thickness of Ventilating material at the remaining portions thereof, overlocking stitching securing the upper edge of said section to the adjacent edge of the crown, and concealed stitching securing the lower edge of the Ventilating section to the sweatband, said Ventilating section being formed of loosely woven fabric having substantially the same cap-shaping properties as the material of the crown.

4. In a cap, a fabric sweatband comprising an outer sweatband section and a similar inner sweatband section, a pleated crown having its lower edge inserted between said sections and stitched thereto, and a pair of spaced Ventilating sections in the crown, each of said Ventilating sections being of substantially the same height as that of the pleats therein, and of substantially the same width along one of its edges as the height thereof, and each of said Ventilating sections comprising a series of warp threads and weft threads interwoven with the warp threads to provide substantially square interstices therebetween, and a twisted thread interwoven with the warp and weft threads and maintaining said threads against displacement to maintain the sizes of the openings in said section unchanged under stress put upon the cap.

5. In a cap, a pleated crown of a single piece of material, a sweatband secured to the lower edge of said crown, part of the material of said crown being omitted to provide an opening therein, and a textile fabric Ventilating section secured in the opening by stitching securing its upper edge to the crown and its lower edge to the sweatband, said Ventilating section comprising loosely woven warp and weft threads providing a multiplicity of openings therein, and said section being of substantially the same height as the pleats in the crown and substantially of the same width as said pleats along at least one edge of said section.

6. In a cap, a one-piece fabric crown having a plurality of spaced pleats therein, a sweatband comprising a pair of similar sections, the lower edge of the crown being secured lby concealed stitching between the upper edges of said sweatband sections, and a Ventilating section of substantially the same height and width as that of the pleats of the crown secured along its upper edge to the crown and along its lower edge between the sweatband sections, said Ventilating section comprising textile fabric woven of thicker threads than that of the crown fabric and thereby having substantially the same flexibility and capsupporting properties as the crown fabric.

'7. In a cap provided with a. pleated crown, a. Visor, and a head band joining the crown and the Visor, a pleated Ventilating section in the crown providing a plurality of thicknesses of Ventilating material at the pleat thereof, stitching securing the upper edge of said section to the adjacent edge of the crown, and concealed stitching securing the lower edge of the Ventilating section to the head band, said Ventilating section being formed of loosely woven fab-ric.

8. In a cap, a one-piece fabric crown having a plurality of spaced pleats therein, a head band at the lower edge of the crown, concealed stitching securing the lower edge of the crown to the upper edge of the head band, and a Ventilating section inserted in the crown and secured along its upper edge to the crown and along its lower edge to the head band, said Ventilating section comprising textile fabric woven of thicker threads than that of the crown fabric.
